It is not penetration based on expanded diameter,...it is penetration based on two different bullets... one acting like a FMJ and the other as mushrooming pancake.
Do you not get what I am saying!!!!!!!
You have changed two variables....
One being the bullet, two being the FPS....
Of course the 1800 fps penetrated further and it is not counter intuitive, YOU ARE SHOOTING TWO DIFFERENT BULLETS !!!! yes the same grain, but the frontal areas are completely different.
WHAT DO YOU NOT UNDERSTAND!!!
Is it supposed to be surprising, enlightening, mind boggling or something to the rest of us, that you have developed a theory that a 160 grain non expanding bullet with a small frontal area will out penetrate a 160 grain bullet with a giant frontal area, and do such with less force, push, momentum, speed, speed impact momentum, or whatever term you come up with....,????
That is as simple as it gets...people understand this.... or at leat I think they do.
You didn't need to use 1800 fps at all.
at 2689 fps you simply compare a bullet with a giant frontal area, to one with a minute frontal area, and the same simple point is proven....but you changed the speeds in an attempt to manipulate the information to support your oppinion that less speed is better .... the folly of it all, is that the point you are proving is outdated, of little real world use and 99% moot.
Here's my theory...
If I throw a dart at my dartboard side ways, but very hard.
and then throw another dart pointy end first, but only half as hard, the pointy dart throw, though only thrown half as hard, will dig in further....
Look At me everyone...Look at me...I have a new theory...!!!!!
Ta ddaaaaaaa!
Darts thrown at dartboards sideways don't dig in as well as darts thrown horizontally pointy end first!!!! even with less power behind the throw, they still dig in further...
I call this the " pointy endy thingy of the dart" theory....
BOW TO ME>>>BOW TO ME I SAY !!!!!!
I am a physics master!!!!
Seriously guys, if you believe my point that Traps' theory is not actually some new theory or new formula,... just a very simple physics lesson in penetration, ...mainly that an aerodynamic non expanding bullet with little frontal area can out penetrate a non aerodynamic mushroom with large fronatal area at a given or even less fps, can ya gibve me a "X2"
cause i really think that most of us somehow inherently know this,...don't we?
This comparison is of two different bullets, the only thing in common is the grains,....moot to the power of moot...
